3 Claims. (Cl. 16o-151) My invention relates towindow shades or blinds and refers particularly to so-called Venetian blinds.

One of the objects of my invention is Venetian blind-s in which the shutters are positioned vertically, thus decreasing the deposit of dust and` dirt thereon and rendering them more 'easily cleaned than is possible with horizontally positioned shutters.

Another object of my invention is Venetian blinds-.in which the light passing therethrough when the shutters are partly opened will be disis possible with horizontal shutters. v Another object of my invention is Venetian blinds which can be pivotally moved entirelyv away from the windows, thus. allowing free access of air and light therethrough andv exposing the entire window' for cleaning purposes.

Another object of my inventionis Venetian blinds in which the shutter can be overlapped and abutted upon each other thus preventing all light from passing through.

Another object 'of my inventionA is Venetian blinds in which it is not necessary to lift the weight of the blind in opening it. f

Another object of my invention is Venetian blinds in which they cannot crash to the bottom because' of the failure of the maintaining mechanism to work.

Another object of' my invention is Venetian olinds in which several'movem'ents 'of the operating cord to fasten it in a desired'position are not necessary. 'f

The generally employed 'Venetian blinds consist of a series of horizontal shutters, or thin slats or" During this performance, the weight of at least r; v;

a portion oi the blind must be raised, and the fastening means is uncertain of operation, frequently resulting in a `crashing and breaking of thedevice."

As the shuttersl of these devices are positioned 4..

horizontally, they catch dirt and dust, which is difficult to remove because of the small spaces between the` shutters, and, inl fact',l it is frequently necessary to lremove the blind from the window frame in order to clean them properly.

dinary shutters, the light and air are directed either upwardly or downwardly when they are partly open, instead of transversely across the room; which latter would result in' a more uniform l,

In exposing the window for cleaning purposes, the entire weight of the blind must be raised to its uppermost position, where it covers an upper portion of the window and which is liable to fall if attemptsv are made to move it away from the window pane.

The above mentioned are'some ofthe disadvantages incident to the usually employed Venetian blinds, all ofvwhich, and other objectionable features, vare not present in the Venetian blinds of my invention, as will be evident from a consideration of my specication and its accompany"- ing drawings.

In the accompanying drawings illustrating one form of' a deviceof my invention, similar parts are represented by similar numerals.

Figure 1 is a front elevation of oneform of my device and window frame partly broken away and with the shutters in closed position.

Figure 2 isa horizontal section through the line 2, 2 of Figure 1.

Figure 3 is a horizontal section similar to Fig ure 2 with the shutters open.

Figure '4 is a fragmentary horizontal section of the device of Figurel with the shutters assembled at one end thereof as explained later.

Figure 5 is an enlarged fragmentary View of the swingable end of the device shown in Figure 1.`

Figure 6 is an enlargedfragmentary View lof the pivotable end of the device of Figure 1.

Figure 'I is an enlarged vertical section through the line 1, 'I of Figure 5. v

The devicebf my invention shown in the accompanying drawings is shown in operation with a window frame having the top member A, the two side members B and C and the bottom member D. Said window frame carries the two vertically movable window sashes E and F, respectively carrying glass window panes G and H, the construction of the window frame and of the window sashes as shown being the usual type and are not a part of my invention. K

The device of my invention, asshownin the drawings, comprises a hinge I0 attached to the frame C and having two extended arrns II, Il, a pintle I2 extending through the member IIJ and the terminal portion of each arm l I'having an opening I3 therethrough. The lower arm ll has a pivotally attached angular member I 4 by means of the eyelet` I5 passing through its opening. I3,

Because of the horizontal position of in@ or- Said member I4 having an opening I6 in its terminal portion.

One terminal end portion I1 of a lazy tong is pivotally attached to the upper arm I I by means of the eyelet I8 and the other terminal end I9 is pivotally attached to the lower arm II by the eyelet 20 passing through the lopening I6..

A loop-shaped member 2l is pivotally attached at 22, to the upper terminal arm 23 at the other end ofthe lazy tong, said loop being adapted to be removably placed in a hook 24 attached to the frame member B.

Each upper pivotal member 2S ,ofthe lazy tong has an extended ring-shaped member 21 xedly attached thereto, and each lower ring-shaped member 28 of the lazy tong has an extended ring-shaped member 29. A rod 30 passes through each pair of superimposed ring-shaped membersy 21 and 29. Each rod 3D passes also through one or more ring-shaped member 3l revolvably carried by its rod 30.

It will be noted that because of the angular member I4, the upper angular points ofthe v'lazy tong will move in a straight horizontal line when thelazy tong is opened and` closed, while the lower angular points of the lazy tong will move downwardly over the rod 30 -during 'its opening and closing movements.

The device carries a pluralityof aligned shutters 32, 32. Each pair of adjacent `shutters lare attacld kto each other by one or more `hingesflll, 4D, so positioned as to allow the members of each pair to abut upon eachother when the shutters are open, as shown .in Figure 3, and Ato :overlap 'each other when they are shut, as shown in Figure 2.

This movement of the shutters is raccon'iplished :by a cord '33, operating as follows: 'The'member v2l has an opening i314. The cord .33 `passes through the opening 34, then through an opening in shutter .32A-,and is affixed to the 'face of shutter 32B -wlfiichshutters are hinged together by hinge 40, thus lforming a pair yof hinged shut- 'ters 32A and 32B. This yconstruction is shown particularly in Figures 3 and 4. Itis ,evident-that `When the cord 33 is moved to 'the left as vsl'iovvn in Figures 3 and 4, the twoshutters 32A :and 32B will be moved into abutment Yupon eachother.

The cord 33 then passes through lan opening in shutter 32C and is aihxedto the face of shutter 32D, which Vshutters vare hinged `together by hinge 140, thus forming a pair of hinged shutters 32C and 32D. It is evident that when 'the movement ofthe cord33 is-.continued yto the left, ,the shutters 32C vand ,32D -Will .be .abutted vupon each other.

',Ihe cord 33 is vthus continued through, `and attached to, the remaining pairs kof shutters, and is then passed through an .opening 3l in .the vhinged member I 0. A stop member .3.3 is carried by the terminal lportions of .the cord ,33 to limit the movement thereof.

It is evident that `when the cord .3.3 is moved 4to the left, the device YWill be shown .as in Figure 3 and .the shutters Will .permit the passage of air and light therethrough, .and when the cord 33 is moved toward the right the shutter will prevent the passage of air and light therethrough as shown in Figure 2.

When it is desired to expose the entire window for purposes of cleaning, or :for otherv reasons, 1the loop-.shaped member Y2l is removed from the hook 24 and the lazy tong collapsed, thus bringing all the shutters together at the free end of the device as shown in Figure 4, and the device is then revolved upon the hinge l0, thus vbringing the device at right angles to the plane of the Window.

While I have shown and described my device with a window lframe having an upper Window sash and a lower Window sash, yit is evident that it can be applied to a Window frame supported by a single window sash.

I do not limit -myself to the particular size, shape, number or arrangement of parts specificent 4 cally disclosed and described, as these may be varied without going beyond the scope of my invention.
